1 Claim.

This invention relates to coil winding machines and more particularly toa counting mechanism for indicating when a predetermined .number ofturns have been wound by the machine in the manufacture of a given coil.

In winding coil units in which numerous circuits are incorporated andprovided with individual terminals, or in which are embodied groups ofwindings difiering in the size of wire, number of turns, or points atwhich terminals must be connected, it is essential for the operator tobe able to determine at any given instant the exact stage of thewinding. An object of this invention is to provide a mechanism of thetype described constructed and arranged to indicate the completion ofany predetermined number of turns or fraction of turns at successivepoints in the winding of any given coil.

A further object is to provide a turn counting mechanism having animproved arrangement of parts which are simple and rugged inconstruction and reliable and accurate in operation.

These and other objects which will be apparent to those skilled in thisparticular art are accomplished by means of the invention illustrated inthe accompanying drawings in which- Fig. 1 is a view in elevation of aturn counting mechanism constructed in accordance with one embodiment ofthis invention, parts being broken away to show certain details ofconstruction, and

Fig. 2 is a transverse sectional view on the line 2-2 of Fig. 1.

Fig. 3 is a view in elevation of an index finger.

The particular embodiment of the present invention which has been chosenfor illustration includes an indicating disc secured to the extended hub6 of a worm gear I rotatably mounted on a supporting stud B secured inone arm 9 of a U-shaped frame Ill which is pivoted to a supportingbracket I I on a frame supporting bolt I2. The beveled periphery I3 ofthe disc 5 is provided with a circumferential series of outwardlyextending slots I4 adapted to receive index fingers l5 for cooperatingwith a marker I6 or pin positioned on the bracket II adjacent theperiphery of the indicating disc. The slots are spaced apart a distanceequal to the amountof rotation of the disc for each turn of wire wound.

A handle I1 is formed on or connected to the U-shaped frame I0 formoving the same about the supporting pivot l2 for the purpose ofconnesting or disconnecting the disc driving worm gear I with a drivingworm l8 on a counter shaft I9 which is driven through the gearing 20'from the winding spindle 2| of the associated coil winding machine. Apivoted latch arm 22 is 6- mounted on the bracket II for engaging thehandle to hold the gear I and worm I8- in driving connection, and aspring 23 is connected to the handle for raising the gear I todisconnect it from the worm when the latch 22 is released. The indexfingers are provided with points 24 which extend laterally from theassociated finger so as to be offset from the longitudinal axis of thefinger. As a result of this arrangement a given finger can be mounted inany predetermined slot so that the point will lie in the axis of theslot as indicated at 25' in Fig. 1, to the right of the slot asindicated at 25" or to the left of the slot as indicated at 25',depending upon whether the pin is placed in a slot so as to position theofiset point in a line with the associated slot, or to the right, or tothe left, respectively. The formation of the point is such that whenextending laterally as indicated at or 25' it cooperates with the markerIt to 25 indicate the completion of a fractional number of turns whenopposite the marker 16, while when employed as shown at 25' it indicatesthe completion of a whole number of turns when it reaches a positionopposite the marker. Hence, if it is required that a certain windinghave 80 turns, for example, or that a tap shall be applied to a windingat the end of 80 turns, an index finger would be so located that itspoint would cooperate with the marker IE to indicate the completion of80 /2 turns, as shown at 25", at which stage in the winding the operatorwould stop the machine, to connect the necessary terminal, to change thetype of wire or to perform any other requisite operation. On the otherhand, when a coil winding having 89 turns, for example, is required, orit is desired to apply a tap or the like to a winding at the end of 89turns, an index finger l5 will be located in the slot numbered 89 withthe point 24 in line with the axis of the slot, as shown at 25'. Thenwhen the disc reaches a position in which the point is opposite thestationary marker IS the operator knows that exactly 89 turns have beenwound. Similarly, if it should be again necessary to stop the machineafter winding say 93 turns, an index finger would be located in the slotnumbered 94 with the point turned to the right as indicated at 25". Thepoint 24 would then be positioned exactly half way between the slotsnumbered 93 and 94, and when moved by rotation of the disc to a positionopposite the stationary marker l6 would indicate the completion of 93turns.

In the illustrated embodiment, the disc 5 has slots I4 which aredesignated in numerical order on the face of the disc by a suitable dialor scale, and the gearing between the disc and the winding spindle 2| ofthe associated machine is in the ratio of 100 to 1, so that onerevolution of the winding spindle rotates the disc 5 a distance exactlyequal to the distance between adjacent notches l4.

A revolution counter 30 for indicating the number of revolutions of thedisc 5 is positioned .on the frame IO' and connected to the disc throughgearing 3| and shaft 32 secured to the extended hub 5 of the drivinggear I. It will be apparent that in the present arrangement, in whichthe disc 5 revolves once for every hundred turns, that the counter 30will indicate hundreds of turns. 4

In the operation of the device the dial is set at zero and the handle I!moved to connectthe disc 5 with the driving mechanism, the latch 22serving to hold the handle I! in such position. Operation of the machineproduces rotation of the disc 5 in which the operator has placed theindex fingers l5 to indicate the successive points in the winding ofthecoil at which terminals are to be connected, or other operationsperformed in accordance with coil specifications. As the coil is wound,the disc 5 is rotated and the operator isable to stop the machine at thepredetermined successive points in the winding of the coil as indicatedby the movement of the successive index fingers to positions oppositethe marker IS. The distance between the center of each slot l4 equalsthe amount of rotation of the disc for each turn of coil wound. Obvious-14 1y, any number of index fingers can be employed to indicate anynumber of successive points in a given coil. The counter is reset byreleasing the latch 22 and disconnecting the driving mechanism to permitfree turning of the disc to 1! any desired starting point.

I claim as my invention:

The combination in a turn counting mechanism of a rotatable machinedriven disc having a plurality of index fingers receiving slots formed mtherein, a stationary marker associated with the circumference of saiddisc, and an index finger having an axially offset index point, saidfinger being adapted to be located in one of said slots with said pointin alignment with said slot or with said point located at one side ofsaid slot to cooperate with said stationary marker for indicating thecompletion of a predetermined number of complete or fractional turns.
